* \brief
|
|
* Fixed-size Names
|
|
*
|
|
* dns_fixedname_t is a convenience type containing a name, an offsets table,
|
|
* and a dedicated buffer big enough for the longest possible name.
|
|
*
|
|
* MP:
|
|
*\li The caller must ensure any required synchronization.
|
|
*
|
|
* Reliability:
|
|
*\li No anticipated impact.
|
|
*
|
|
* Resources:
|
|
*\li Per dns_fixedname_t:
|
|
*\code
|
|
* sizeof(dns_name_t) + sizeof(dns_offsets_t) +
|
|
* sizeof(isc_buffer_t) + 255 bytes + structure padding
|
|
*\endcode
|
|
*
|
|
* Security:
|
|
*\li No anticipated impact.
|
|
*
|
|
* Standards:
|
|
*\li None.
